For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.

Referring to fig. 1-12, the present embodiment provides an automatic heating furnace, which includes a heating furnace body 1, and a feeding device is disposed at a front end of a furnace inlet of the heating furnace body 1. The feeding device comprises a lifting mechanism 2, a longitudinal conveying mechanism 3 and a transverse conveying mechanism 4. And the material lifting mechanism 2, the longitudinal conveying mechanism 3 and the transverse conveying mechanism 4 are sequentially arranged along the conveying direction of the material.

In the present solution, as shown in fig. 11 and 12, the lifting mechanism 2 includes a fixed frame 21 and a material-carrying cart 22 for carrying material. The fixed frame 21 is provided with a guide rail 23 along the height direction thereof, and the guide rail 23 is provided with a pulley in a sliding way, and the pulley is connected with the material carrying vehicle 22. Meanwhile, the upper end of the fixed frame 21 is provided with an electric hoist 24, the electric hoist 24 is connected with the material carrying vehicle 22 through a connecting rod 25 arc-shaped plate, the upper end of the connecting rod 25 arc-shaped plate is connected with the electric hoist 24, and the lower end of the connecting rod 25 arc-shaped plate is hinged with the bottom end of the material carrying vehicle 22. The material loading trolley 22 is driven by an electric hoist 24 to move up and down along the guide rail 23 in cooperation with the pulley. The guide rail 23 is divided into a linear guide rail 231 and a curved guide rail 232 from bottom to top. After the material loading vehicle 22 enters the curved guide rail 232, the material loading vehicle 22 deflects relative to the center of the curved guide rail 232, so that the material loading vehicle 22 is inclined towards the longitudinal conveying mechanism 3. And the material loading vehicle 22 is lifted by the electric hoist 24, the position of the material loading vehicle 22 in the curved guide rail 232 is different according to the lifting height of the material loading vehicle 22. The position of the carriage 22 in the curved track 232 is different, and the inclination angle of the carriage 22 is different. The greater the angle of inclination of the cart 22, the more material is discharged. The lifting height of the material carrying vehicle 22 is controlled by controlling the electric hoist 24, so that the inclination angle of the material carrying vehicle 22 is controlled, and finally the material discharging quantity and the material discharging speed are controlled.

Referring to fig. 1, 2 and 10, the longitudinal conveying mechanism 3 includes a feeding box 31, and a feeding port of the feeding box 31 is connected to the lifting mechanism 2. The material 5 poured by the loading vehicle 22 enters the box from the feed opening of the feed box 31. The lifting assembly 32 is arranged in the feeding box 31, specifically, the lifting assembly 32 includes a plurality of movable plates 321, and the plurality of movable plates 321 are arranged in a step shape from low to high in the vertical direction. The height difference between every two adjacent movable plates 321 is greater than the height of the material 5. And the bottoms of the plurality of movable plates 321 are fixedly connected through a connecting plate 322, and the bottom end of the connecting plate 322 is connected with a lifting cylinder 323. The plurality of movable plates 321 are driven by the lifting cylinder 323 to move up and down simultaneously. In this scheme, the two sides of each movable plate 321 are provided with a guide column 324, and the guide columns 324 are fixedly connected with the inner wall of the feeding box 31. The movable plate 321 is slidably connected to the guide posts 324. Meanwhile, a fixed plate 325 arc-shaped plate 413 is arranged between every two adjacent movable plates 321, two sides of the fixed plate 325 arc-shaped plate 413 are fixedly connected with inner walls of two sides of the feeding box 31, and the upper plate surface of the movable plate 321 and the upper plate surface of the fixed plate 325 arc-shaped plate 413 are inclined surfaces which extend towards the direction of the highest movable plate 321 and are obliquely arranged downwards.

A guide plate 326 is provided at the inlet of the inlet box 31, and the material 5 poured out by the material lifting mechanism 2 falls on the guide plate 326 and is guided by the guide plate 326 to fall on the upper end surface of the first movable plate 321 (the movable plate 321 located at the lowest position). Then, the lifting cylinder 323 drives the first movable plate 321 to ascend, and further drives the material 5 to ascend, so that the material 5 slides to the upper end surface of the arc-shaped plate 413 of the next fixed plate 325 and slides downwards along with the upper end surface of the arc-shaped plate 413 of the fixed plate 325 until abutting against the plate surface of the second movable plate 321. Then, the lifting cylinder 323 drives the first movable plate 321 to descend, and the second movable plate 321 descends accordingly, so that the second movable plate 321 is spliced with the arc-shaped plate 413 of the fixed plate 325 to receive the downward-sliding material 5, and the process is sequentially circulated until the last movable plate 321 drives the material 5 to ascend, and the material 5 slides down to the transverse conveying mechanism 4.

It should be noted that, although the number of the movable plates 321 is three in the present embodiment, the number may be four, five, or more than five, and the number of the movable plates 321 is not limited herein.

In this scheme, as shown in fig. 1 and fig. 8, the transverse conveying mechanism 4 includes a supporting seat 41, and a first conveying belt 42 for receiving the material 5 pushed by the movable plate 321 and conveying the material 5 is disposed on the supporting seat 41. When the last moving plate 321 drives the material 5 to rise and the material 5 slides down to the belt surface of the first conveying belt 42, the first conveying belt 42 drives the material 5 to perform a feeding motion.

The tail end of first conveyer belt 42 is equipped with first rotation dish 43, is connected with first driving motor 44 with the axle center on the first rotation dish 43 and rotates around self centre of a circle under the effect of first driving motor 44. And a plurality of first accommodating grooves 431 capable of accommodating single materials 5 are uniformly distributed on the first rotating disc 43 along the circumferential direction. When the first receiving groove 431 rotates to the end of the first conveying belt 42 along with the rotation of the first rotating disc 43, the first receiving groove 431 receives the material 5 on the first conveying belt 42 and rotates continuously. While during the rotation the following material 5 is always against the wall of the first rotor disc 43. After the movable plate 321 pushes the material 5 into the first conveying belt 42, the material 5 is stacked on the first conveying belt 42, and each first accommodating groove 431 can receive a single material 5, but it cannot be ensured whether the material 5 is still stacked on the upper end of the material 5, and the material 5 is divided into multiple rows by the first rotating disc 43 and then conveyed in a spaced manner.

And the two sides of the first conveying belt 42 are provided with limiting plates 45 and arc-shaped plates 413, and the limiting plates 45 and arc-shaped plates 413 on the two sides are tangent to the first rotating disc 43. Because the first conveyor belt 42 is continuously operated, the subsequent material 5 moves forward, and the material 5 in front is blocked by the wall of the first rotating disc 43, so that the subsequent material 5 is forced to move towards two sides, and the arc-shaped plate 413 of the limiting plate 45 prevents the material 5 from being separated from the first conveyor belt 42.

The side wall of the supporting seat 41 is further provided with a supporting plate 46, and a bearing piece 47 is fixedly connected to the supporting plate 46. The receiving member 47 provides a bottom support for the first rotary disc 43 and the material 5 in the first receiving groove 431 under the first rotary disc 43. The receiving member 47 is provided with a material passing channel 48 penetrating through the upper and lower end surfaces of the receiving member 47. When the first receiving groove 431 containing the material 5 rotates to above the material passing channel 48, the material 5 falls into the material passing channel 48.

As a preferred embodiment, referring to fig. 3-8, the material passing channel 48 is divided into a reduced diameter section 481, a straight section 482 and a buffer section 483 from top to bottom. The inner diameter of the material passing channel 48 at the upper end of the reduced diameter section 481 is larger than the inner diameter of the material passing channel 48 at the lower end of the reduced diameter section 481, and the inner diameter of the material passing channel 48 at the reduced diameter section 481 gradually decreases from the upper end to the lower end. And the inner diameter of the material passing channel 48 in the straight section 482 is the same as that of the lower end of the reduced diameter section 481 and can only receive one material 5. The inner diameter of the material passing channel 48 at the upper end of the reducing section 481 is larger than the inner diameter of the material passing channel 48 at the lower end of the reducing section 481, so that the material 5 is prevented from interfering with the first rotating disc 43 in the process of falling into the material passing channel 48 from the first rotating disc 43 (namely, the upper end of the material 5 is positioned in the first accommodating groove 431 and the lower end of the material 5 is positioned in the material passing channel 48) to influence the rotation of the first rotating disc 43. After entering the reducing section 481, the material 5 slides down along the inner wall of the reducing section 481 and enters the straight section 482. And only one material 5 can be accommodated by the inner diameter of the straight line segment 482 so that the materials 5 are aligned one by one in the vertical direction. Meanwhile, the material passing channel 48 extends obliquely and downwardly from the buffer section 483, and an included angle is formed between the buffer section 483 and the straight line section 482. The materials 5 are buffered by the buffer sections 483 extending obliquely downwards, so that the materials 5 are prevented from directly impacting objects below the bearing parts 47, and the service life of the device is prolonged. And the side wall of the receiving part 47 is provided with a baffle 473 at the material passing channel 48 for limiting the material 5 in the material passing channel 48, and the material 5 is prevented from leaking through the baffle 473.

In this embodiment, as shown in fig. 6 and 7, an opening 471 is formed in the upper end surface of the receiving member 47, and the first drive motor 44 is incorporated in the opening 471. So as to reduce the occupied area of the equipment and improve the utilization rate of the air.

Meanwhile, a second rotating disc 49 is arranged below the bearing piece 47, a second driving motor 410 is coaxially connected to the second rotating disc 49, and the second driving motor 410 is connected with the supporting plate 46. The service life of the second rotary disk 49 is increased by the above-mentioned damping section 483. And the second rotary disk 49 is rotated around its center by the second driving motor 410. The axial direction of the second rotary disc 49 is perpendicular to the axial direction of the first rotary disc 43, and a plurality of second accommodating grooves 491 which can receive single materials 5 are arranged on the disc wall of the second rotary disc 49 along the circumferential direction. When the second accommodating groove 491 rotates with the second rotating disc 49 to the discharge port of the material passing channel 48, the second accommodating groove 491 receives the material 5 in the material passing channel 48 and rotates continuously. And the wall of the second rotating disc 49 abuts against the discharge opening of the material passing channel 48. The material 5 falling subsequently is blocked by the wall of the second rotating disk 49, and only when the next second accommodating groove 491 rotates to the discharge hole of the material passing channel 48, the next material 5 can enter the second accommodating groove 491 to rotate along with the rotation. Since the first rotary disc 43 has divided the material 5 into a plurality of rows and then the material 5 is conveyed row by row at intervals, the material 5 separated by the second rotary disc 49 is a single material 5.

As a preferred embodiment, the discharge port of the material passing channel 48 is an arc opening 471 which can be fitted with the tray wall of the second rotating tray 49, and a through groove 472 is provided on a side wall of the receiving element 47 in the feeding direction of the second rotating tray 49, and the through groove 472 is communicated with the material passing channel 48. The discharge hole through the material passing channel 48 is an arc-shaped opening 471 which can be attached to the disk wall of the second rotating disk 49, so that the subsequent materials 5 are prevented from overflowing from the gap between the material passing channel 48 and the second rotating disk 49.

And as shown in fig. 9, the depth of the second receiving groove 491 is smaller than the height of the material 5, and the length of the through groove 472 is smaller than the height of the material 5. But the length of the through slots 472 plus the depth of the second holding tank 491 is greater than the height of the material 5. It will be easily understood that when a single material 5 falls into the second rotary disk 49, if the depth of the second receiving groove 491 is greater than the height of the material 5, a portion of the lower end of the next material 5 falls into the second receiving groove 491. Since a part of the next material 5 is in the material passing passage 48 and a part of the next material 5 is in the second accommodating groove 491, the material 5 interferes with the second rotary disk 49 to effect rotation during the rotation of the second rotary disk 49. If the length of the through slots 472 is greater than the height of the material 5. Subsequent material 5 will overflow from the vat. While the depth through the second receiving groove 491 is smaller than the height of the material 5, the length of the through groove 472 is smaller than the height of the material 5, but the length of the through groove 472 plus the depth of the second receiving groove 491 is larger than the height of the material 5. After the material 5 falls into the second holding tank 491, the material exceeds the second holding tank 491, and the subsequent material 5 is prevented from falling into the second holding tank 491. And during the rotation process, the material 5 is matched with the through groove 472 to rotate away from the adapting piece 47, and interference cannot occur.

A second conveyer belt is arranged below the second rotating disc 49 for receiving the materials 5 in the second accommodating tank 491 and conveying the materials 5. When the second rotating disc 49 rotates to a certain angle, the material 5 automatically falls onto the second conveying belt from the second accommodating groove 491 under the action of gravity. The tail end of the second conveyer belt is provided with a pushing assembly for pushing the materials 5 on the second conveyer belt to enter the heating furnace body 1. Specifically, the pushing assembly comprises a pushing cylinder and a pushing plate 412, and the pushing plate 412 is connected with the pushing cylinder and pushes the material 5 on the second conveying belt to enter the heating furnace under the action of the pushing cylinder. The chain that is used for carrying material 5 is arranged in the heating furnace, and the material 5 that is pushed into the heating furnace body 1 by the pushing assembly is received through the chain and is carried.

It will be readily appreciated that if the materials 5 are delivered at spaced intervals, subsequent materials 5 move to the pushing position of the second conveyor belt as the pusher plate 412 pushes the materials 5 into the warming oven. When push cylinder drives push pedal 412 and moves back, push pedal 412 will touch material 5 on the promotion position, takes place to interfere, and material 5 will promote towards opposite direction, leads to the waste of material 5, and the cylinder also feeds easily and leads to damaging. And the materials 5 are stacked and enter the heating furnace, the materials 5 are mutually contacted, and the contacted parts cannot be fully heated. In the scheme, the materials 5 are divided into multiple rows through the first rotating disc 43 before entering the heating furnace, and the materials 5 are conveyed at intervals row by row. And then the materials 5 in the same column are divided into a plurality of rows by the second rotating disc 49, and the materials 5 are conveyed to the second conveying belt one by one, so that the problem that the push plate 412 interferes with the subsequent materials 5 is avoided. And the materials 5 which finally enter the heating furnace one by one to be heated. Avoid appearing a plurality of materials 5 and piling up the problem that the concurrent heating leads to the heating insufficient. So that the material 5 is heated more fully and more uniformly after entering the heating furnace.

In this embodiment, an arc-shaped plate 413 is connected to the push plate 412. When the pushing cylinder drives the pushing plate 412 to push the material 5 on the second conveying belt, the arc-shaped plate 413 moves to one side of the second rotating disc 49, and the inner arc surface of the arc-shaped plate 413 is attached to the disc wall of the second rotating disc 49 to limit the material 5 in the second rotating disc 49. When the push cylinder drives the push plate 412 to reset, the arc-shaped plate 413 is far away from the second rotating disc 49. Because the opportunity that push cylinder promoted push plate 412 falls into the second conveyer belt (being the slew velocity of second rolling disc 49) with material 5 and is difficult to realize complete synchronization, equipment is after long-time operation, and material 5 inevitably appears and falls into the second conveyer belt and carries to pushing position, but push plate 412 still is doing the problem that promotes the action and lead to taking place to interfere. In this scheme, when the push pedal 412 promoted material 5 and got into the stove of heating, the arc 413 removed the one side of second rolling disc 49 and forms spacingly to material 5 in the second rolling disc 49, prevents that material 5 from falling out, only under material 5 rotated to second rolling disc 49, just can fall on the second conveyer belt, postpones the time that next material 5 removed the promotion position, avoids taking place to interfere. When the second rotating disc 49 rotates to the position where the material 5 can fall on the second conveyor belt and the push plate 412 does not push, the material 5 directly falls on the second conveyor belt, so that the time for moving the next material 5 to the pushing position is shortened, and the interference is avoided.

In addition, the scheme also comprises a controller, a third driving motor and a temperature sensor. The temperature sensor is arranged on the heating furnace body 1, and the third driving motor is connected with the chain to drive the chain to run. And the third driving motor and the temperature sensor are respectively connected with the controller. When the temperature sensor detects that the temperature of the materials in the heating furnace body 1 on the chain is lower than a preset value, the third driving motor is controlled by the controller to drive the chain to run at a reduced speed. The structure and driving method of the heating device, the third driving motor and the chain in the heating furnace body 1 are conventional devices and common knowledge, and therefore, they will not be described herein. The specific process of detecting the temperature of the materials in the heating furnace body 1 on the chain by the temperature sensor can refer to the steel pushing type natural gas forging heating furnace with the application number of 2013105 70040.5.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, without departing from the spirit of the present invention, a person of ordinary skill in the art should understand that the present invention shall not be limited to the embodiments and the similar structural modes without creative design.
